Title: Improvements in or relating to piezoelectric transducers
IPC: B06B1/06
Filed: 1958-12-04
Abstract: 901,494. Piezo-electric elements. RENAULT, P. Dec. 4, 1958 [Dec. 6, 1957], No. 39131/58. Class 40 (8). A piezo-electric transducer device has two electrodes separated by a body portion of a piezo-electric material, one of said electrodes comprising a metallization of one of the faces of said body portion, and the other a grid at the opposite boundary of said portion, and a further body portion possessing piezo-electric or damping properties extending from the grid in the direction away from said one electrode. In one embodiment, Fig. 3, for use in testing materials by ultrasonic pulses, the piezo-electric material 1, e.g. ceramic, is metallized on one face 3 opposite the face 2 engaged with the material to be tested and contains three grids 5, 6 and 7, e.g. of platinum wire, of sufficiently large mesh to minimize reflections. One grid serves to apply an electric energizing signal, another to apply a D.C. polarizing voltage, and the third to receive the echoes. In a simple arrangement (Fig. 2, not shown), a single grid is provided and may be used for both energization and polarization. In Fig. 4, the metallized layer 3 is a disc located opposite an aperture in a grid 5 to still further reduce reflections. In Fig. 5, the face 3 is not metallized and metallization 8 on one face of a thin portion 1 of piezoelectric material is protected by a coating 2, e.g. of polyvinyl chloride. Above the grid 5 is a ceramic damping block 9 and a further damping block 10. French Specification 137,085 is referred to.
Patent GB-1039861-A (GB)
Title: Improvements relating to composite fibrous materials
Inventor: WINCHCOMBE JOHN JEREMY
IPC: D04H3/009
Filed: 1962-10-17
Abstract: A composite material composing a fibrous constituent and a flexible or rigid polyurethane foam constituent is made by introducing into an assembly of fibres first a liquid composition representing one part of a polyurethane-foam-forming mixture and subsequently a vapour representing the complementary part of the polyurethane-foam-forming mixture, the vapour comprising at least one ingredient necessary for the polyurethane foam reaction, and then allowing the liquid composition and the vapour to react and form a polyurethane foam within the assembly of fibres.  The fibrous assembly may be a matted web of crimped continuous nylon 66 fibres, a knitted stretch fabric of bulked nylon 66 yarn or a woollen blanket material.  The assembly may be needled before impregnation and may be compressed or moulded during or just after foaming.  The vapour may comprise steam or an amine catalyst, e.g. triethylamine or N-methyl-morpholine.  The fibrous assembly carrying the liquid composition may be suspended or supported in a vessel containing the vapour.  Alternatively, the vapour may be formed in situ from the liquid phase of the substance in question.  The liquid composition may comprise a liquid reaction product of an organic polyiso(thio)cyanate and an organic compound having two or more isocyanate-reactive groups, this reaction product still having -NCO (or -NCS) groups available for reaction.  The liquid composition may take the form of a solution of the active ingredients in an indifferent solvent, e.g. methyl ethyl ketone, into which the fibrous assembly is dipped.  Examples are given in which the following substances are mentioned as ingredients of the liquid composition: liquid urethane rubber, 2:4-tolylene diisocyanate, 2:6-tolylene diisocyanate, a mixture of trimethylolpropane and hexanetriol, a solution of triethylene diamine in dry acetate, water-soluble silicone, trimethylopropane predissolved in methyl ethyl ketone, stannous octoate, and a solution of triethylene diamine in polypropylene glycol diol. The liquid composition may be spread on to one surface of the fibrous assembly with subsequent application of a doctor blade. The liquid is evenly distributed throughout the assembly by mangling during which the assembly is held between two polyethylene or polypropylene films.  To produce an artificial leather having surfaces corresponding to the "grain" and "flesh" surfaces of natural leather, the fibrous assembly may comprise two fibrous webs superimposed one upon the other and the structure obtained when the polyurethane-foam-forming reaction has taken place may then be separated into two layers corresponding to the individual two webs; the layers obtained may be treated again individually by the method of the invention.  Alternatively, the assembly of fibres is moulded during formation between an impervious surface and a porous surface.

Filed: 1964-09-29
Abstract: 1,072,986. Semi-conductor devices. PHILCOFORD CORPORATION. Sept. 29, 1964 [Sept. 30, 1963], No. 39684/64. Heading H1K. Semi-conductor material is deposited on an area of a semi-conductor wafer by forming a masking band of oxide on the wafer around the area and then epitaxially depositing semi-conductor material on the area. The band must be narrow enough to prevent formation of crystallites thereon. In a typical case a wafer of N-type silicon the surface of which is inclined at 0À5-4 degrees to a 111 crystallographic plane is etched and a thermal oxide film grown on it. The film is removed by photolithographic techniques except from areas 14, 16, 18 and 30 (Fig. 3). After further conventional cleaning steps the wafer is blown dry in nitrogen and placed in a reaction chamber. It is raised to 1200-1400 C. by R.F. heating while the chamber is flushed out with hydrogen. P- type silicon is then deposited on the unmasked areas from a flow of hydrogen containing silicon tetrachloride and boron tribromide and the wafer afterwards cooled in flowing hydrogen. The surface is next reoxidized and holes formed in the oxide to expose areas to which contact is made by metal vapour deposited through a mask to provide a series of interconnected PN diodes (Fig. 9, not shown). Alternatively the new oxide layer is selectively removed by photolithography to re-expose areas within the original rings 14, 16 and N-type silicon deposited thereon from a mixture of silicon tetrachloride, phosphorus trichloride and hydrogen. The surface may again be reoxidized and suitable contacts made through holes in the oxide to the resulting transistor zone configurations.
